The following changes may be responsible: src\gnuwin32\fixed\Makefile lines 31 and 47 where version 9 has '-e "s|BINPREF =|BINPREF = $(BINPREF)|" \' and version 10 has '-e 's|BINPREF =|BINPREF ?= $$(RTOOLS)gcc492_64/bin/|' \'.
Or, it may have been the addition of "RTOOLS ?= C:/Rtools/" on line 17 of src\gnuwin32\fixed\etc\Makeconf in version 10. There are 31 other files with differences, but they do not seem to have bearing.
